Electronic device, storage medium and method for protecting the electronic device

Abstract

In a method for protecting an electronic device, a voltage threshold value is set for indicating that water has entered the electronic device. A voltage value is detected from each water sensor included in the electronic device at a predetermined time interval. The method determines whether water has entered the electronic device according to the detected voltage value of water sensor and the voltage threshold value. When water has entered the electronic device, the method further prompts a user of the electronic device using a predetermined prompt mode, and controls the electronic device to be powered-off.
